The returning flight to the US they did not dim the lights so that it was comfortable to sleep. A red light was shining down on my head most of the trip because I had a window seat. It was very annoying.

Food was actually pretty decent for both dinner and breakfast that was served. There was also a wide variety of movies/tv/music to listen to on your personal tv.

An economy seat on a long flight is never going to be very comfortable, and most of the flight I was very cold but I was lucky to have a seat with extra leg room.

I would expect when I book a Luftansa flight to fly in a Luftansa jet. This flight was carried by United and I did not know that until I arrived at the airport.

Staff was great

getting off the plane was very time consuming despite being already landed. Not entirely sure why but this was the first time getting off a plane took some time. im sure the staff was working hard but I’m unsure why it took some time.

The flight from EWR to Oslo was delayed by over 2 hours which meant I would miss my next connection... and I understand that happens sometimes.
But, it was after hours on the airline number phone number and the fly.com customer service could not help with finding an alternate connection from Oslo to FRA. It was frustrating to then have to wait at Oslo airport for another 4 hours before the new connecting flight.

Could check my suitcase earlier (arrived at airport too early). I had a bit off over 23 kg but that did not pose any problem.
Boarding was quiet fast and almost with timetable. The food was good and service provided pleasant.
I was happy that we landed safely providing bad weather in Toronto that evening.

the flight attendants were very nice.

the fact that my carry on bag was broken when we landed in Poland and no one from the staff took even a second to guide us about what can we do about it. the entertainment system was not good at all and the movie section was poor. our flight from TLV to Poland was canceled and they didn't know about it until 4 hours before the flight!!! Not sure I will fly with this airline again in the future.

SAS has introduced hand luggage measurement and weighing at checkin, for a maximum of 17.5 lbs or 8 kg. SAS does not care if you have flown on another transatlantic carrier, which allows more than 8 kg. Then you need to start emptying your hand luggage at checkin. The whole checkin process was a big mess, the contract employees eg. at Heathrow do not help much (they probably do not do this to any other airline). SAS staff does not remind you to take your IDs and passport, medications etc. from your hand luggage, which is then checkedin luggage as opposed to hand luggage. It is obvious that transatlantic passengers have more hand luggage than many local passengers.

Flight attendance kept waking me up to lift my seat so the passenger behind me can "enjoy their vegetarian meal". After I requested not to be disturbed ever again with that kind of requests, they woke me up for breakfast again. I was the only passenger around that they requested to pull my seat.
